The 34-year-old made his surprise announcement on the ITV show where he was appearing alongside Robert Lindsay to promote the musical they are currently starring in together.

When he told Jonathan Ross he had a secret to share, the presenter joked that perhaps he was going to come out as gay.

Hound replied: "'If I was gay I would be completely super proud of that! What I am about to come out about is worse.

"I think I'm going to run as an MEP... I'm as confused by this as you are.

"I am going to run for the NHA. The NHA is the National Health Action party because the NHS is being privatised and I feel like ’who is stepping forward and telling people about it’ and nobody is.

"I was sat with my wife and my wife was like well we should do something.

"And a month later she said you know that thing about us doing something, I think we might be those people that sit around going why isn't somebody doing something and it might be that we actually have to do something.

"So I think I'm going to end up running as an MEP."

Hound later tweeted a link to a blog post which he said he hoped "explains everything".

In it, he wrote: "The millionaires that currently run things have decided that you (assuming you’re not a member of the Bullingdon Club, or a trustafarian) can go f*** yourself.

"This place is for them, not you. Why should you get free healthcare?

"Why can’t they take that big pot of money ear-marked for medicine and just start sharing it out amongst themselves?

"People are desperate when they’re sick and nothing’s as easier to monetise than desperation.

"Big, rich, private heathcare companies have donated millions to the Conservative party and now they’re calling in the debt. Jeremy Hunt is killing the NHS so that his owners can bleed you dry."
